Discarding the Razor, Ratifying the Drift: Identity-Protective Reasoning and the Institutional Entrenchment of Contested Certainties in Addiction Treatment and Policy

The addiction field is unusually rich in durable, contested certainties: that confrontation breaks through denial, that medication treatment merely substitutes one drug for another, that a single treatment philosophy fits all, or, conversely, that any criticism of a favored model reflects stigma rather than evidence. This conceptual article introduces two linked constructs to explain how such certainties survive contrary evidence. Occam’s Disposable Razor (ODR) names a bounded micro-level event: the moment at which a simpler, coherent, evidence-consistent explanation is available and is nonetheless discarded because accepting it threatens identity, belonging, authority, safety, or an inherited narrative, with parsimony, noncontradiction, and falsifiability abandoned together. Ratified Reality Drift (RRD) names the macro-level process by which the protected interpretation is repeated, institutionalized, and inherited as taken-for-granted reality within families, recovery communities, treatment organizations, and policy systems. We distinguish the constructs from motivated reasoning, cognitive dissonance, belief perseverance, groupthink, and the normalization of deviance; specify a nine-stage coding frame with explicit criteria for an ODR attribution; and apply the framework symmetrically to patients, families, mutual-aid communities, clinicians, and institutions, including both critics and defenders of the brain disease model and of medications for opioid use disorder. We separate defensive discarding from legitimate skepticism and from protected private meaning, address the risk that the construct could itself be weaponized, and derive eight falsifiable propositions with associated research designs. The framework has not yet been tested empirically; its contribution is a symmetrical, testable research program for a familiar clinical intuition.
